To all whom it may concern:

Be it known that I, JAMES F. MORRISON, a citizen of the United States, residing at Chicago, in thecounty of Cook and State of Illinois, have invented new and useful Im rovements in Brake-Shoes, of which the fol owing is a specification.

This invention is an improvement on in Patent No. 786,373, dated April 4, 1905; and its object is to provide for securin the body of a brake-shoe within a cast maleable iron shell in a simple and permanent manner.

With these and other ends in view the iu-i vention consists in the novel improvement illustrated in the accompanying drawings, in

which- Fi ure 1 is a side elevation of a shell for a car-shoe embodying the invention. Figs. 2

and 3 arerespectively end and back views of'the shoe illustrated in Fig. 1. Fig. 4 is a back view of a shell, showing another embodiment of the invention. Fig. 5 is a sectional view on the line 5 5 of Fig. 4. Fig. 6 is a longitudinal sectional view of a composition shoe embodying the invention. F i 7 ,is'a

I employ a cast'malleable iron shell 10 to receive-and hold a body of any suitable material. This body may be made of composition 11, Fig. 6, or it may be composite in character and formed of-castiron 12, prov vided with ockets 13 to receive inserts 14 of com osition or metal differing from the body, Fig. 7. The body may also be formed entirely of cast iron or of any other suitable material, and inserts of any suitable character may be located in the composition body or in the metal body and in any desired manner.

The body of the shoe is pressed orcast in the shell, and for the purpose of securing it permanently therein 1 provide the shell with a plurality of openings to receive the material of the body. These openings may be var1- ously arranged and l have shown only a few embodiments of the invention.

Fi 8 is a side elevation of 8. tier embodiment of the inreceive In Figs. 1 and 2 circular o enings 15 are back only or in. the back and sides or in the.

back and ends. I prefer to arrange the open- 6o ingsin stzTggered series, as illustrated in the drawings, and to bevel the walls of each 0 ening so that the body material will ma e 8. looking engagement in the openings with the shell. The attaching-lug 17, the guide-lugs 18, and the end lugs 19 are made integral with the shell.

My improved shell is cast like any ordinary cast-iron'casting and then annealed, and 1t can be easily cast with any number of openings arranged in any desired manner and without increase of cost. While a shell provided with openin s as herein described will be considerabl lig ter in weight than an imperforate shel, as described in my patent 7'5 aforesaid, it will possess all the stren th reand shape.

What I claim, and desire to secure by Letters Patent, is 1. Abrake-shoe com rising a body and a cast malleable iron shell .inclosingthe body and having openings in its sides and ends to ortions of the body.

2. A irake-shoe com rising a body and a cast malleable iron shel inclosing the body and havingopenings with beveled walls there in to receive portions of the body.

3. A brake-shoe com rising a body and a cast malleable iron shell inclosing the bod and provided in its sides, ends and back with openings to receive portions of the body.
